Background: We investigated the efficacy of nutritional support in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer (LAEC).
Methods: Eleven patients treated with CRT for locally advanced esophageal squamous cell carcinoma were included. Oral intake energy expenditure (OIE) and total energy expenditure (TEE) of all patients were calculated. Oral nutrition supplementations (ONSs) were utilized as nutritional therapy for the patients with malnutrition (OIE/TEE<0.6). Enteral nutrition (EN) was used in the patients with tumor obstruction.
Result: Two patients (18.9%) received ONS and 2 other patients received EN. Seven patients were able to take enough energy in the meal. The mean energy charge was increased from 67.9%to 84.9%. Nine patients (81.8%) completed the treatment regimen. During the CRT period, the prognostic nutritional index (PNI) and C-reactive protein level (mg/dL) were not significantly different. The body mass index decreased to 0.39 kg/m2 (p=0.039) and the mean weight loss was 1.57%. The overall response rate was 81.8%.
Conclusion: The nutritional support in the patients treated with CRT for LAEC is effective for maintaining nutritional status. Moreover, the response rate is satisfactory.
